Therefore, it is widely used in various industrial machines.
精密機械の応用分野の中で、製品の軽量化及び体積の縮減が要求されているが、モーターを連結する各種の線材、例えば電線、気管等は必要な構造部品である。従来の減速機の構造において、例えば、台湾特許公開第201333347号には、内部空間が妥当に設計されていないため、上記のような線材は必ず規定外の空間を占用して収容されることで、減速機全体の体積が増加されて、精密機械分野の要求を達成できなかった。
これに鑑みて、どのように前記問題を改善するかが、本発明の最も解決しようとする重要な課題である。
In the field of application of precision machinery, it is required to reduce the weight of the product and reduce the volume. In the structure of a conventional speed reducer, for example, in Taiwan Patent Publication No. 201333347, the internal space is not properly designed. The volume of the entire speed reducer has been increased, and the demand in the precision machinery field has not been achieved.
In view of this, how to improve the problem is the most important problem to be solved by the present invention.
本発明の1つ目の目的は、遊星歯車により減速機構の作動を補助することで、モーター入力端のエネルギー消費を低減することができる中空遊星減速機を提供する。 The first object of the present invention is to provide a hollow planetary speed reducer that can reduce the energy consumption of the motor input end by assisting the operation of the speed reduction mechanism with a planetary gear.
本発明の2つ目の目的は、減速機のために中空の収容空間を提供することで、各種の線材を収容し、これによって減速機の空間配置を最適化し、更に減速機全体の体積を縮減することができる。 The second object of the present invention is to provide a hollow housing space for the speed reducer to accommodate various wires, thereby optimizing the space arrangement of the speed reducer and further reducing the volume of the speed reducer. Can be reduced.
図1〜図6に示されたように、本発明における中空遊星減速機は、本体1を有し、該本体1上には同一軸線11に沿って設けられている第1歯車21、第2歯車31とサンギヤ32が設置されており、該第1歯車21と該第2歯車31はそれぞれ該本体1の両側に位置して、第1減速機構2及び第2減速機構3を構成している。 As shown in FIGS. 1 to 6, the hollow planetary speed reducer according to the present invention has a main body 1, and a first gear 21 and a second gear provided on the main body 1 along the same axis 11. A gear 31 and a sun gear 32 are installed, and the first gear 21 and the second gear 31 are located on both sides of the main body 1 to constitute the first reduction mechanism 2 and the second reduction mechanism 3, respectively. .
前記第2歯車31は内歯車である。詳しく説明すると、該第2歯車31は環状構造体で、かつ内側表面には歯が設けられている。そのため、該第2歯車31の内側は他の歯車と噛合して連結されている。 The second gear 31 is an internal gear. More specifically, the second gear 31 is an annular structure, and teeth are provided on the inner surface. Therefore, the inside of the second gear 31 is engaged with and connected to other gears.
図1、図2と図６に示されたように、本実施例の中で、該第1歯車21は内歯車で、第1減速機構2において、該第1歯車21の内側には少なくとも１つの駆動歯車22が設けられ、各駆動歯車22は動力入力源4により駆動される。本実施例で、該動力入力源4は4つのモーター41を含み、該4つのモーター41は１つのモジュールに組合されて、それぞれ駆動軸42が延伸される一方、該第1歯車21の内側には4つの駆動歯車22が設けられて、それぞれ駆動軸42に対応して連結されることにより、各駆動歯車22の回転を駆動している。各駆動歯車22はそれぞれ伝動歯車23に連結され、各伝動歯車23はそれぞれ歯車21に連結される。該伝動歯車23と該第1歯車21はそれぞれ該本体1に枢設されているため、モーター41が該駆動歯車22の回転を駆動する時、該伝動歯車23の伝動によって、該第1伝動歯車21が連動して回転する。本実施例で、該駆動歯車22の歯数は該伝動歯車23の歯数より少なく、かつ該伝動歯車23の歯数は該第1歯車21の歯数より少ないため、モーター41の出力回転速度が2回減速される。 As shown in FIGS. 1, 2, and 6, in the present embodiment, the first gear 21 is an internal gear, and in the first speed reduction mechanism 2, at least one is disposed inside the first gear 21. Two drive gears 22 are provided, and each drive gear 22 is driven by the power input source 4. In this embodiment, the power input source 4 includes four motors 41, and the four motors 41 are combined into one module, and the drive shaft 42 is extended respectively while the first gear 21 is disposed inside the first gear 21. The four drive gears 22 are provided and connected to the drive shafts 42 to drive the rotation of each drive gear 22. Each drive gear 22 is connected to a transmission gear 23, and each transmission gear 23 is connected to a gear 21. Since the transmission gear 23 and the first gear 21 are pivoted on the main body 1, when the motor 41 drives the rotation of the drive gear 22, the transmission of the transmission gear 23 causes the first transmission gear 23 to rotate. 21 rotates in conjunction. In this embodiment, since the number of teeth of the drive gear 22 is less than the number of teeth of the transmission gear 23 and the number of teeth of the transmission gear 23 is less than the number of teeth of the first gear 21, the output rotational speed of the motor 41 is Is decelerated twice.
上述により、本実施例は第1減速機構2において、4つのモーター41が同時に駆動されるため、従来の１つのモーターが作動する減速機に比べて、各モーター41の回転する時の回転ねじりモーメントが低減され、更に起動時と運転時のエネルギー消費が削減されることができる。更に、歯数が該駆動歯車22と該第1歯車21の歯数の間にある伝動歯車23が該駆動歯車22と該第1歯車21の間に設けられることにより、該駆動歯車22が比較的低い回転ねじりモーメントで該伝動歯車23を駆動することができ、該第1歯車21を直接駆動する該駆動歯車22に比べて、エネルギー消費を低減させる効果を実現している。 As described above, in the present embodiment, since the four motors 41 are simultaneously driven in the first reduction mechanism 2, the rotational torsional moment when each motor 41 rotates as compared to the conventional reduction gear that operates one motor. In addition, energy consumption during startup and operation can be reduced. Further, a transmission gear 23 having a number of teeth between the number of teeth of the drive gear 22 and the first gear 21 is provided between the drive gear 22 and the first gear 21, so that the drive gear 22 is compared. The transmission gear 23 can be driven with a relatively low rotational torsional moment, and an effect of reducing energy consumption is realized as compared with the drive gear 22 that directly drives the first gear 21.
しかし、前記第1歯車は他の実施例の中で、図３に示されたような外歯車の構造形態を形成することができる。図３により、該第1歯車21Bの外周側には歯部が設けられ、かつ該外周側は他の歯車と噛合して連結されるため、同じく前記第1減速機構2の効果を実現することができる。 However, the first gear may form an external gear structure as shown in FIG. 3 in other embodiments. According to FIG. 3, since the tooth portion is provided on the outer peripheral side of the first gear 21B and the outer peripheral side is engaged with and connected to other gears, the effect of the first reduction mechanism 2 can be realized. Can do.
図４、図５と図６に示されたように、第2減速機構3において、該サンギヤ32は該第2歯車31の内側に位置し、かつ該第2歯車31と同一平面に設けられている。図2に示されたように、該サンギヤ32は連結部材5により該第1歯車21に連結されることで、該第1歯車21と一体になって同期して回転される。本実施例の中で、該連結部材5は該軸線11に沿って延伸する連結部51を有し、該連結部51の一端は拡張して該第1歯車21に連結される。図4、図5に示されたように、該サンギヤ32は少なくとも２つの遊星歯車３３に連結されており、本実施例の中で、遊星歯車33の数は4つで、各遊星歯車33はそれぞれ該第2歯車31に連結される。該第2歯車31は該本体1に固定されて動けない状態になっているため、各遊星歯車33は該サンギヤ32の連動により、該サンギヤ32を迂回する動作を生じる。各遊星歯車33は出力部材6内に設けられ、詳しく説明すると、各遊星歯車33の軸心部は固定部材61により穿設され、かつ該出力部材6に固定されることにより、当遊星歯車33は前述のように該サンギヤ32を迂回して回転する時、同時に該出力部材6を連動して回転させることができ、また、該出力部材6は外部装置に接続（図には示していない）されることも可能で、出力端を形成して該外部装置を連動して回転させることができる。 As shown in FIGS. 4, 5, and 6, in the second reduction mechanism 3, the sun gear 32 is located inside the second gear 31 and is provided in the same plane as the second gear 31. Yes. As shown in FIG. 2, the sun gear 32 is connected to the first gear 21 by the connecting member 5, and is rotated integrally with the first gear 21. In this embodiment, the connecting member 5 has a connecting portion 51 extending along the axis 11, and one end of the connecting portion 51 is expanded and connected to the first gear 21. 4 and 5, the sun gear 32 is connected to at least two planetary gears 33. In this embodiment, the number of planetary gears 33 is four, and each planetary gear 33 is Each is connected to the second gear 31. Since the second gear 31 is fixed to the main body 1 and cannot move, each planetary gear 33 operates to bypass the sun gear 32 by interlocking with the sun gear 32. Each planetary gear 33 is provided in the output member 6. More specifically, the planetary gear 33 has a shaft center formed by a fixing member 61 and fixed to the output member 6. As described above, when rotating around the sun gear 32, the output member 6 can be simultaneously rotated in conjunction with the output member 6, and the output member 6 is connected to an external device (not shown). It is also possible to form an output end and rotate the external device in conjunction with it.
前記第2減速機構3の動作の中で、図6に示されたように、該サンギヤ32が該第1歯車21と同軸で連結されるため、その回転速度は第1歯車21と同じであり、即ち、第1減速機構2の減速結果に影響される。引き続いて、遊星歯車33の配置により、回転速度が再び低減され、即ち、該遊星歯車33がサンギヤ32を迂回する回転速度は該サンギヤ32の回転速度より遅い。上述により、該出力部材6の回転速度は前記第1減速機構2と第2減速機構3の作用により、モーター41の出力回転速度より遅い。 In the operation of the second reduction mechanism 3, as shown in FIG. 6, the sun gear 32 is connected coaxially with the first gear 21, so that the rotational speed thereof is the same as that of the first gear 21. That is, it is influenced by the deceleration result of the first deceleration mechanism 2. Subsequently, the rotational speed is reduced again by the arrangement of the planetary gear 33, that is, the rotational speed at which the planetary gear 33 bypasses the sun gear 32 is lower than the rotational speed of the sun gear 32. As described above, the rotation speed of the output member 6 is slower than the output rotation speed of the motor 41 due to the action of the first reduction mechanism 2 and the second reduction mechanism 3.
それ以外に、この減速機本体1には中空管部材7が設けられ、その内部は一収容空間71を有して、線材、例えば電線、気管などを収容することができる。本実施例の中で、該中空管部材7は該連結部材5の連結部51内に設けられ、その延伸方向は該軸線11と重なる。該中空管部材7を設置して線材を収容することで、減速機内部の空間配置が最適化される効果が得られ、減速機全体の占用体積を有効的に縮減し、製品の小型化目的を達することができる。 In addition, the speed reducer main body 1 is provided with a hollow tube member 7, and the inside thereof has one accommodating space 71, which can accommodate a wire, for example, an electric wire, a trachea and the like. In this embodiment, the hollow tube member 7 is provided in the connecting portion 51 of the connecting member 5, and its extending direction overlaps the axis 11. By installing the hollow tube member 7 and accommodating the wire, the effect of optimizing the space arrangement inside the reducer is obtained, effectively reducing the occupied volume of the entire reducer, and reducing the size of the product You can reach your goals.
